采用理论分析、数值模拟及试验验证相结合的研究手段，建立更精细考虑界面效应的拟动力子结构试验方法。首先，基于Guyan缩聚法和界面自由度缩减思想，构建可靠、易于实现的精细化子结构界面信息传递方法；其次，采用编译软件与子结构数据接口技术，编制用于数值模拟分析的试验程序，对不同模型分别进行拟动力和拟动力子结构数值模拟比较分析，建立由子结构边界简化引起的系统误差模型，进行累积误差的分析与控制研究，探索得到控制该累积误差的方法；然后，针对多自由度非线性耦合的力-位移混合控制方法，研究对不同模型的控制效果，并最终建立多自由度非线性耦合的力-位移混合控制参数设计方法。最后，基于上述研究成果开发出一套更精细考虑界面效应的拟动力子结构试验模块，通过缩尺钢框架模型拟动力子结构物理试验，验证上述研究成果的科学性和可靠性，从而提供更能真实反应结构地震行为的可靠试验技术，进一步推动结构抗震试验方法的发展。

The method for the substructure pseudo-dynamic test considering the refined interface effect is established by combining the theoretical analysis, numerical simulations and experimental verifications. In the first place, the easily realizable and reliable refined substructure interface information transfer method is established based on the Guyan reduced method and interfacial reduced technique. In the second place, using the compile software and the substrutural data interface techniques the test program for numerical simulations is compiled. By comparing the results between the substructure pseudo-dynamic numerical simulation and pseudo-dynamic numerical simulation test for different models, the model for system errors, brought by the simplification of the substructure interface, is built and at the same time, the method for controlling the cumulative error is given. Then, the control effect of the multi-degree of freedom(MDOF) nonlinear coupled force-displacement mixed control method on different models is studied, thus the design method for the MDOF nonlinear coupled force-displacement mixed control parameters is established. Finally, based on the above research results, the program module for the substructure pseudo-dynamic test considering the refined interface effect is developed and at the meantime, the effectiveness and reliability is validated through the substructure pseudo-dynamic physical test of the scale steel frame model. Through the research of this project, we will provide a more reliable test technology to reflect the seismic behavior of the structure, thus play a role in promoting the development of the seismic test method.
